Don't mean to be a typical geezer/curmudgeon here--although I AM--but when seeing such things I cannot but help think of all the idyl time and brainpower involved and wonder if those involved might not better put their time & energy to use more fruitfully, like seeking a cure for cancer, picking up litter in the city parks, etc...........I know, I know, "beauty is its own reward" etc .Still. Bah Humbug!
